Steps for solving 3x+18=54 are shown explain how step 1 solve the equation.

Option C is correct

Subtracting 18 from both sides isolates the variable term

Step-by-step explanation:

Given an equation:

Subtract 18 from both sides we get;

Step 1.

Simplify:

Step 2.

Divide both sides by 3 we have;

Step 3.

Simplify:

Step 4.

x = 12

Therefore, Subtracting 18 from both sides isolates the variable term in step 1 helps to solve the equation.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
